LOOM-SI-IUTTLE.

Application filed December 8, 1915.

To all whom it may concern:

Be it known that I, SHANKER AB'A I BHI- SEY, a subject of His Majesty, the King of Great Britain, and resident of London, England, have invented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification.

This invention relates to improvements in loom shuttles. and has for its object to provide a shuttle designed to obviate the practice known as kissing the shuttle.

Hitherto many attempts have been made to produce shuttles where the necessity for sucking the thread through the delivery eye of the shuttle is obviated. and for this purpose shuttles have been slotted in various ways to enable the thread to be passed to the delivery eye. These prior propositions have failed in practice. however, on account of the slots being so arranged that their apices being either upon or adjacent the center line of the shuttle peg or delivery eye, one of the slots had to cross the top edge of the shuttle and so coming when in operation more or less parallel to the loom threads are liable to catch or break the thread. Moreover owing to such a position of the slot its edges could neither be rounded or made one higher than the other without making an objectionable gap which in practice would be very liable to catch the'threads.

The object of my present invention is to obviate these defects, and the invention consists in so slotting the shuttle that while the thread from the shuttle bobbin can be readily passed through the slot to the delivery eye there is no exposed edge or slot which can be engaged by the loom or other threads.

In order to accomplish the objects of my invention it is necessary that the thread from the shuttle bobbin should be able to be readily passed to the delivery eye, but it is also necessary that the slot should be so formed and located that no edge can be presented to the threads under or by which the shuttle oscillates. In general the best contour which the slot can take is of something approximating a V shape so that the lines of the slot are more or less at right angles to the loom threads when the shuttle is in operation.

My present invention consists in giving v the slot a particular location and curvature. In accordance with my lnvention the slot proceeds approximately from the center line Specification of Letterslatent.

of the top of the shuttle and then falls away from the center line so that its angle or apex is substantially on a line running from the edge of the shuttle to its tip or apex and from this point the slot returns and runs to the delivery eye. By this means the peninsular like member defined by the slot lies diagonally of the shuttle body, and owing to such a position the tip of such peninsular like member can easily be dipped into the recess formed between the angle, the edges of which become slightly higher than the depressed tip over which the threads easily glide without being caught by the slot.

My invention will be best understood upon reference to the accompanying drawings wherein I have illustrated a shuttle constructed in accordance with my invention.

In these drawings Figure 1 is an elevational view of the edge of the shuttle end with the shuttle turned upon one of its lower edges.

Fig. 2 is a section on line AA of Fig. 1 looking in the direction of the arrow.

Fig. 3 is a side elevational view.

Fig. 4% is a section on line BB of Fig. 3

looking in the direction of the arrow.

Fig. 5 is a sectional view of the shuttle end on line C'C of Fig. 1.

Fig. 6 is a plan view of the blank of a convenient form of delivery eye.

Fig. 7 is an elevational view of the delivery eye rolled up and ready for insertion in position.

Fig. 8 is a perspective View of the delivery eye ready for fixing-- in'iposition.

Referring to these drawings wherein like numerals of reference indicate corresponding parts throughout, the numeral 1 designates the shuttle body provided with the usual bobbin spindle 2 upon which a cop or bobbin 3 is carried in the usual manner. This shuttle body is slotted in the following manner: The upper line of the slot proceeds from approximately a central point 4 substantially in line with the bobbin spindle but from this point curves away from the apex of the shuttle so that the upper line of the slot instead of running straight toward the center of the apex falls away to one side and then at or about the position 5 where the metallic tip 6 commences, turns and runs back to the delivery eye 7. There is thus a continuous slot running around and under a peninsular part 8 of the shuttle body and the angle 9 at the end of this peninsular like part would be approximately bisected by a line running from the upper edge of the shuttle to the apex of the shuttle, and the extremity of this peninsular like part dips into the concave recess 10 which accommodates the peninsular like part of the shuttle body and this extremity is below the edges of the slots of the shuttle so that it can offer no obstruction to the loom or other threads. The peninsular like part 8 is rounded upon its edges and the edges of the concave recess 10 are similarly smoothed and are ust a shade higher than the part 8. The slot, from its upper lines, is preferably not cut vertically but at an incline toward the return line of the slot. That is to say, the underside of the part 8 conforms to the concave recess 10 under which there is a channel 12 but its underside is preferably rounded off somewhat, shown clearly in Fig. 4. By reason of this the thread from the bobbin when drawn in the upper line of the slot at once passes underneath the extremity of the 'icninsular like part of the shuttle body as is indicated by the chain line 13 in Fig. 1, and thus auton'iatically enters the return slot leading to the delivery eye 7 which of course it enters. It will be understood that the slot may be formed entirely in the shuttle body as hereinbefore described and illustrated or a separate member of any suitable material may be utilized to form the peninsular like member 8. The delivery eye may be of any suitable form, but a convenient form of eye is that illustrated in Figs. 6, 7 and S. This eye consists of a rolled up stamping 15 provided with a slot 16 into which the opposite extremity 1'? of the stamping enters as is clearly illustrated in Fig. 7. This stamping can be easily pressed into the opening 18 in the shuttle body and the prongs or spikes 19 will hold it securely in place as will be readily understood. The stamping is preferably formed from a blank such as is illustrated in Fig. 6.

What I claim and desire to secure by Letters Patent is l. A loom shuttle having a substantially V-shaped slot leading in one direction approximately from the center of the top of the shuttle. to a point approximately upon a line passing from the edge of the shuttle through the apex of the shuttle, and returning from this point in the other direction and terminating in an enlarged opening, a delivery eye positioned within the enlarged opening, the delivery eye comprising a strip of metal having an elongated opening formed adjacent one end thereof, the opposite end tapering to a pointand lying within the elongated opening, the tapering portion lying in the same plane with the slot to form a continuation thereof, and means integral with the delivery eye for securing the same within the shuttle body.

2. A loom shuttle having a substantially l-shaped slot therein, the slot extending from a point adjacent one end of the shuttle to a point substantially centrally thereof, one end of the slot terminating in a circular opening, a delivery eye positioned within the circular opening, the delivery eye comprising a strip of metal having an opening adjacent one end thereof, the opposite end. tapering to provide a pointed guide, the metal being curved to permit thepointed guide to extend through the opening of the eye, and form a substantially V-shaped guide adjacent the end of the delivery eye, the V-shaped guide lying in the same plane with the V- shaped slot for guiding a thread passed through the slot into the delivery eye, and integral spurs formed on one side of the delivery eye for securing the delivery eye Within the shuttle.

In testimony whereof I aflix my signature.
